This document summarizes key information about evaluation versions of Windows Server® 2012, including where to obtain them, the limits on their use, and how to convert them to full retail versions. It also summarizes the supported upgrade paths from previously licensed retail versions of Windows Server to Windows Server 2012.

Evaluation versions of Windows Server 2012

Fully functional time-limited evaluation versions of Windows Server 2012 are available for the following editions:

Windows Server 2012 Standard

Windows Server 2012 Datacenter

Windows Server® 2012 Essentials

These evaluation versions are 64-bit only and can be installed with the Server Core option or the Server with a GUI option. For more information about these installation options, how to convert between them, and how to use the new Minimal Server Interface and Features on Demand, see http://technet.microsoft.com//library/hh831786.

For all editions, you have 10 days to complete online activation, at which point the evaluation period begins and runs for 180 days. During the evaluation period, a notification on the Desktop displays the days remaining the evaluation period (except in Windows Server 2012 Essentials). You can also run slmgr.vbs /dlv from an elevated command prompt to see the time remaining.

Limits of evaluation versions

All evaluation versions are fully functional during the evaluation period, although booting to Safe mode is not available. The Windows Server 2012 Standard and Windows Server 2012 Datacenter editions come with the activation key pre-installed. After the 180-day evaluation period elapses, the server warns you in various ways depending on the edition:

Windows Server 2012 Standard; Windows Server 2012 Datacenter:

The following warning appears on the Desktop: Windows License is expired

When you log on to Windows, you are prompted with the following options:

Activate now

Ask me later

The system shuts down every hour.

The only updates that can be installed are security updates.

Event ID 100 from source WLMS “The license period for this installation of Windows has expired. The operating system will shut down every hour.” appears in the Application log.

Windows Server 2012 Essentials: you receive warnings on the Desktop and on the dashboard, but the server does not shut down.

Most evaluation versions can be converted to full retail versions, but the method varies slightly depending on the edition. Before you attempt to convert the version, verify that your server is actually running an evaluation version. To do this, do either of the following:

From an elevated command prompt, run slmgr.vbs /dlv; evaluation versions will include “EVAL” in the output.

From the Start screen, open Control Panel. Open System and Security, and then System. View Windows activation status in the Windows activation area of the System page. Click View details in Windows activation for more information about your Windows activation status.

If you have already activated Windows, the Desktop shows the time remaining in the evaluation period.

If the server is running a retail version instead of an evaluation version, see the “Upgrading previous licensed versions” section of this document for instructions to upgrade to Windows Server 2012.

For Windows Server 2012 Essentials: You can convert to the full retail version by entering a retail, volume license, or OEM key in the command slmgr.vbs.

If the server is running an evaluation version of Windows Server 2012 Standard or Windows Server 2012 Datacenter, you can convert it to a retail version as follows:

If the server is a domain controller, you cannot convert it to a retail version. In this case, install an additional domain controller on a server that runs a retail version and remove AD DS from the domain controller that runs on the evaluation version. For more information, see http://technet.microsoft.com/library/hh994618.aspx.

Read the license terms.

From an elevated command prompt, determine the current edition name with the command DISM /online /Get-CurrentEdition. Make note of the edition ID, an abbreviated form of the edition name. Then run DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula, providing the edition ID and a retail product key. The server will restart twice.

For the evaluation version of Windows Server 2012 Standard, you can also convert to the retail version of Windows Server 2012 Datacenter in one step using this same command and the appropriate product key.

Upgrades from pre-release versions of Windows Server 2012 (such as the Release Candidate) are not supported. Perform a clean installation to Windows Server 2012.

Upgrades that switch from a Server Core installation to the Server with a GUI mode of Windows Server 2012 in one step (and vice versa) are not supported. However, after upgrade is complete, Windows Server 2012 allows you to switch freely between Server Core and Server with a GUI modes. For more information about these installation options, how to convert between them, and how to use the new Minimal Server Interface and Features on Demand, see http://technet.microsoft.com/library/hh831786.

If you do not see your current version in the left column, upgrading to this release of Windows Server 2012 is not supported.

If you see more than one edition in the right column, upgrade to either edition from the same starting version is supported.

Per-server-role considerations for upgrading

Even in supported upgrade paths from previous retail versions to Windows Server 2012, certain server roles that are already installed might require additional preparation or actions for the role to continue functioning after the upgrade. The following table summarizes these considerations.

Server role

Upgrade information

Active Directory

Active Directory Domain Services (AD DS): Active Directory domains can be upgraded by upgrading the operating system of existing domain controllers or by replacing existing domain controllers with domain controllers that run Windows Server 2012. For more information, see Deploy Active Directory Domain Services (AD DS) in Your Enterprise (http://go.microsoft.com/fwlink/?LinkId=262195).

You can perform an in-place upgrade from either Windows Server 2008 or Windows Server 2008 R2 to Windows Server 2012. After completing upgrade of your operating system for any servers running the AD RMS server role, you will need to run the AD RMS Upgrade wizard to upgrade your AD RMS cluster and ensure consistency. Otherwise, your AD RMS cluster might not be in a consistent state. The only other consideration when upgrading that you should be aware of when upgrading from these versions of the Windows Server operating system is that if the Windows Internal Database (WID) was previously selected for use to support your AD RMS database needs, that configuration will block your upgrade to Windows Server 2012 and require you to take additional steps. To unblock your upgrade to Windows Server 2012 you must first uninstall the AD RMS server role and migrate the existing WID instance to a SQL Server instance. For more information, see http://go.microsoft.com/fwlink/?LinkId=229299.

After you upgrade a Windows Server 2008 R2-based server that has DFS Management installed, you must reinstall the DFS Management Tools on the server. To install the DFS Management Tools, run the following Windows PowerShell cmdlet as an administrator: Install-WindowsFeature RSAT-DFS-Mgmt-Con

You can also use the Add Roles and Features Wizard in Server Manager. On the Features page of the wizard, expand Remote Server Administration Tools, expand Role Administration Tools, expand File Services Tools, and then select the DFS Management Tools check box.

Routing and Remote Access Service (RRAS) was a role service in Windows Server operating systems prior to Windows Server 2012 that enabled you to use a computer as an IPv4 or IPv6 router, as an IPv4 network address translation (NAT) router, or as a remote access server that hosted dial-up or virtual private network (VPN) connections from remote clients. Now, that feature has been combined with DirectAccess to make up the Remote Access server role in Windows Server 2012. For information about migration from Windows Server 2008 R2 and other versions prior to Windows Server 2012, see http://technet.microsoft.com/library/hh831423.aspx

Active Directory-based Activation cannot be used with non-Microsoft directory services.

AD DS must be at the Windows Server 2012 schema level to store activation objects. Domain controllers running earlier versions of Windows Server can activate clients after their schemas have been updated using the Windows Server 2012 version of Adprep.exe. For more information, see What's New in Active Directory Domain Services Installation and Removal.

Web Server (IIS)

No functionality has been removed or changed. Web applications that work in IIS 7.0 run normally in IIS 8.0.

Converting existing Windows Server 2012 versions

At any time after installing Windows Server 2012, you can run Setup to repair the installation (sometimes called “repair in place”) or, in certain cases, to convert to a different edition.

You can run Setup to perform a “repair in place” on any edition of Windows Server 2012; the result will be the same edition you started with.

For Windows Server 2012 Standard, you can convert the system to Windows Server 2012 Datacenter as follows: From an elevated command prompt, determine the current edition name with the command DISM /online /Get-CurrentEdition. Make note of the edition ID, an abbreviated form of the edition name. Then run DISM /online /Set-Edition:<edition ID> /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula, providing the edition ID and a retail product key. The server will restart twice.

For Windows Server 2012 Essentials, you can run Setup and convert it to Windows Server 2012 Standard by providing the appropriate retail license key.
